The company noted that the move marks the culmination of over 2 years of solid work involving the preparation of a detailed Mine Plan, extensive baseline field and desk environmental studies.
"We are delighted to have reached this final stage in the permitting process and, whilst there have been a number of delays to the process, the end result is a robust environmental assessment,” Patrick Cheetham, Sunrise executive chairman said in a statement.
He added: “A highlight of the EA is the contribution of our Project to a reduction in carbon emissions. This comes from from the replacement of Portland cement with CS natural pozzolan and which, at the maximum planned production rate of 500,000 tons per year, gives an annual CO2 reduction equivalent to the average annual CO2 emissions from over 10,400 US households or the carbon sequestered by over 8.2 million tree seedlings grown for ten years."
Cheetham continued: “We will move to initiate first production of perlite and natural pozzolan for larger-scale customer trials as soon as possible after we receive a positive permitting decision with the expectation that this will transition to commercial production in due course on the commitment of potential customers to sales contracts."
Sunrise noted that the documents were prepared with extensive consultation with the Bureau of Land Management (BLM) and the Nevada Division of Environmental Protection's Bureau of Mining Regulation and Reclamation (BMRR).
